Red light therapy and infrared therapy are often mentioned together in the world of wellness, hudpleie, and pain relief — and for good reason. They both use light energy to stimulate healing and regeneration in the body. But are they the same thing?
La oss bryte det ned.
Hva er rødt lysterapi?
Rødt lys terapi (RLT) bruker synlig rødt lys bølgelengder, typisk mellom 620nm og 660 nm. These wavelengths penetrate the skin to a shallow depth — around 8 til 10 millimeters — and are known to:
- Stimulate kollagen produksjon
- Forbedre skin tone and texture
- Promote sårheling
- Redusere inflammation on the skin’s surface
- Aid in hårvekst
Because red light is visible to the human eye, RLT often gives off a soft, warm red glow.
What Is Infrared Therapy?
Infrared therapy uses invisible light, specifically nær-infrarød (NIR) bølgelengder, typisk mellom 700nm and 1100nm. These wavelengths penetrate much deeper into the body — up to 5 centimeters (ca 2 tommer) — reaching muskler, ledd, og til og med bein.
Infrared therapy is commonly used to:
- Relieve joint and muscle pain
- Forbedre circulation and oxygenation
- Redusere deep inflammation
- Støtte nerve regeneration and repair
- Forbedre recovery after workouts or injury
Since NIR light is usynlig, these devices won’t appear to glow as brightly as red light therapy panels, though they may still emit some warmth.
Key Differences Between Red and Infrared Therapy
| Trekk | Rødt lys terapi | Infrarød terapi |
|---|---|---|
| Bølgelengde | 620–660nm | 700–1100nm |
| Visibility | Synlig (red glow) | Invisible |
| Inntrengningsdybde | ~10 mm (skin level) | Opp til 50 mm (muskel, ledd, bone) |
| Primary Uses | Hudens helse, anti-aldring, hårvekst | Smertelindring, muskelgjenoppretting, dyp vevsheling |
| Sensation | Warm, glowing | Often no visible light, deeper warmth |
Can They Be Used Together?
Yes — and they often are.
Many modern red light therapy devices combine red and near-infrared wavelengths for maximum therapeutic benefit. This dual-wavelength approach allows the treatment of both surface-level og deep tissue issues in one session.
For eksempel:
- 660nm rødt lys can boost collagen for skin rejuvenation
- 850nm nær-infrarødt lys can reduce joint pain and inflammation deeper in the body
This combination is especially popular in full-body therapy beds and panels.
Siste tanker
Red light therapy and infrared therapy are not exactly the same — but they’re closely related and often work best together. Red light targets surface skin concerns, while infrared goes deeper to relieve pain and support recovery. Whether you’re aiming for younger-looking skin or relief from sore muscles, understanding the difference helps you choose the right device — or combination — for your wellness goals.
